D02MCF is a setup routine which must be called prior to a continuation call to D02NEF
D02MCF is provided to permit you to signal that the next call to D02NEF
is a continuation call. In particular, if D02NEF
exits because the maximum number of integration steps has been exceeded, then a call to D02MCF resets the step counter allowing the integration to proceed.
D02MCF is not threaded in any implementation.
